Which mode is typically used during machine setup and maintenance?

• A. Automatic
• B. Disabled
• C. Manual
• D. Diagnostic

Answer: (C)

During setup and maintenance you need direct, hands-on control of the machine to adjust parameters, calibrate components, and observe how the system responds in real time. Manual mode provides this direct, operator-driven control and prevents automated sequences from running without your initiation, which helps you perform safety checks and careful testing without unexpected actions.

Automatic mode would run the programmed processes automatically, which can interfere with calibration or testing and introduce unexpected changes.

Disabled mode stops operation entirely, so you can’t perform setup or maintenance tasks.

Diagnostic mode is focused on built-in tests and troubleshooting rather than normal setup activities, and it may restrict what you can adjust or observe during maintenance.

So the mode commonly used for setup and maintenance is manual.
